Evaporative coolers are sustainable and energy efficient. They use less electricity to run as they only need to power the fan that draws airflow over the cooling pad. Evaporative coolers automate the basic evaporation to cool your home. They are designed with a fan, a water reservoir, a thick pad, and other extra features to improve efficiency and user experience. The fan draws hot air into the cooler and to the cooler pads. The thick pads absorb water from the reservoir creating a cooler surface area. As the hot water crosses the surface area, it absorbs the water molecules making the temperature drop. The fan then blows the cool air to the room.
